Tax Filing Deadlines and Key Dates for the 2025 Filing Season (Tax Year 2024)

Letting a tax deadline slip past you is one of the quickest ways to turn an ordinary return into a costly mess. Here's the reassuring part: the dates that matter most stay fairly steady year after year, so a bit of planning really does pay off. What follows is a warm, jargon-free walkthrough of the dates you'll want on your radar for the 2025 filing season, which is when you file your 2024 tax year return. We'll stay practical and flag the spots where you should verify the latest specifics, since a date can move when it falls on a weekend or holiday.

One quick heads-up: InstallTurboTax.us is an independent help guide. We have no affiliation with Intuit or TurboTax, and everything here is general guidance. Always confirm the particulars with the IRS and your state tax office.

The deadlines most people need to know

For most individual filers, the date that matters most is April 15, 2025. That's when your 2024 federal return is due and when any tax you owe needs to be paid. A handful of other dates tend to come into play for lots of folks too:

• Late January 2025: This is roughly when the IRS starts accepting e-filed returns. You're free to prepare your return earlier in software, but it usually won't be sent until the IRS formally opens the season.
• January 31, 2025: The typical cutoff for employers and many payers to issue W-2s and most 1099s. If a document still hasn't shown up by early February, contact whoever was supposed to send it.
• April 15, 2025: The primary filing and payment date for most individual taxpayers.
• October 15, 2025: The extended deadline to file if you've requested an extension (we'll get to that next).

Remember too that many states run on their own filing calendar, which may not line up with the federal date. If you owe state tax, take a quick look at your state's website so a federal-only mindset doesn't catch you off guard.

Extensions: more time to file, not to pay

Can't get everything done by April 15? You can ask for an automatic extension that moves your filing deadline out to October 15, 2025. This is a completely ordinary, perfectly legitimate step, and it's a lifesaver when you're chasing down a stray form or just need a little more room to breathe.

Now for the part that catches people off guard every single year: an extension buys you more time to file, but not more time to pay. If you think you'll owe, you should still figure out a reasonable estimate and pay it by April 15 to steer clear of interest and possible penalties. When you submit your extension, the smart move is to send along your best estimate of the balance due.

• File the extension by April 15, 2025.
• Pay as much of your estimated balance as you can manage by that same date.
• Submit the finished return by October 15, 2025.

Estimated taxes and other dates to watch

Are you self-employed, freelancing, or earning meaningful income that doesn't have tax withheld? Then you're probably making quarterly estimated tax payments. For the 2024 tax year, that fourth-quarter payment was generally due around mid-January 2025. Going forward, the 2025 tax year payments land roughly in April, June, and September of 2025, with the last one falling in January 2026. Jot these down early, because they slip people's minds easily.

Two other situations are worth a mention: you can usually fund a traditional or Roth IRA for the 2024 tax year right up until the April filing deadline, and folks serving in combat zones or living overseas may get special extended deadlines. If either of those describes you, confirm the exact dates that apply to your situation.

Tips to file on time and stress-free

The easiest way to stay ahead of these deadlines is to begin pulling documents together in February instead of waiting until the second week of April. Set up a folder, whether on paper or on your computer, and tuck each W-2, 1099, and deduction receipt inside as it lands. Tax software such as TurboTax can import a lot of those forms and guide you through everything step by step, which takes the panic out of the last-minute rush.

If you're picking out a product or plan, think of any prices you come across as ballpark figures. Editions and costs shift around, so check current pricing and features on the official TurboTax website before you buy. And if April 15 somehow sneaks up on you, keep in mind that filing an extension and paying your estimate beats doing nothing nearly every time.
